I'm going to weigh in on this, because I did a lot of research before buying what I did, based on what I was going to use it for. Much the same as the snowmobile market, I believe quad's are dividing up into different segments, such as utility, sport, trail riding, etc. Most do all well, but some excel in different areas and less so in others.
Honda. Its like the elan of the quad world. Simple, tough, reliable. Not the fastest, little to no suspension, and will probably run forever. They haven't really changed much in years, and some people like that, others do not. 420 and under the bikes are still 'small' by today's standards. Solid rear axles, low ground clearance and often with only manual shift options. If you want tried and true, this is an option. However, don't expect to enjoy yourself on a 200km/day trail ride, and invest in a chiropractor. Their newer big bike I've never seen. Apparently it has a automotive style automatic transmission. Can't say if this is good or bad, but in my head, its probably heavy, slow, and expensive to fix. Could be wrong though. Also, none contain a locking front diff. I use diff lock a fair amount, and can't count the times its pulled me out of a jam. I've a friend with a Honda, and I can't found the number of times he wouldn't be stuck if he had one. I feel the need to point it out to him every time, to which I get a sarcastic 'Ha. Ha'
Can Am. They've come a long way in a short amount of time. If you want pure, exhilarating endless torque, these are the answer. They also have a fantastic suspension for trail riding that is smooth, predictable and tough. Most of the complains you hear about people bending frames and breaking things come from driver abuse and error. If driven sensibly, they'll last a long time. I know several nearly or exceeding 10k kms. The only real issue is their belt drive transmission, most have to replace the belt 2-3 times before reaching 10,000 kms, but its am $85 dollar belt that takes a few minutes to replace, just like a snowmobile. If you concerned, carry a few basic tools and a spare. One feature I didn't care for was the brake. There is only one on the handle bar, and it engages all 4 wheel brakes. I prefer independent control of my front or rear braking for technical riding, but that's me. Also, a lack of a front locker. They have a visco-lok or something similar. They work great, until they don't.
Kawasaki/Suzuki. I can't really comment of their newer stuff, but I've seen a few around. Most are from guys looking at a cheaper alternative to a Can Am. If they found it or not I'm not sure, but I can't vote either way on these.
Arctic Cat. Reliable engines, smooth ride, and many, many options. One thing they've got going for them is their transmission that is almost identical to Yamaha's. The way it works is like this. When the engine is running, sitting at idle, the primary clutch does not turn. The belt between the primary and secondary clutch is tight, and there is no slippage. Inside the engine, there is a wet clutch, much the same as the early quads and trikes with manual transmissions have. A set of centrifugal clutches bathed in oil expand with engine rpm to engage the clutch. Once engages, the output shaft begins turning the primary, which turns the secondary with 0 slip. This saves the belt from significant wear, gets more torque to the ground with less heat. On a typical Snowmobile, or other belt driven quads (Can Am, Suzuki, Polaris), when the engine is running, the primary is turning all the time. There is a certain amount of slip that occurs before the clutch is fully engaged and the belt starts to turn with the engine. This builds heat, wearing the belt, but it works. Why the other manufacture's don't adopt the Yamaha/Arctic Cat model is beyond me. Perhaps it saves cost, simplifies some things, I don't know. But to me its a smart system that works well; wet clutches work well, and last practically forever. As for the rest of the bike, They are cheaper, so some fit and finish things are a little low compared to Can-Am or Yamaha. However, they do have the best ground clearance in the industry, the ride is good, now have power steering, and many, many options including a two up model, and have the option for a V-twin engine I believe. Lockable front diff.
Polaris. Cheap, fast, and won't comment on the reliable part. Most polaris guy's swear by them. IN MY EXPERIENCE, I've never seen one that hasn't had a problem. Part of this could be luck, and the other part could be driver abuse/neglect. I do know they have a great ride. They're fit and finish is decent, however being one of the first out there to switch to a belt drive transmission has earned them a sour reputation. Maybe things have improved, but this is one case where I don't think I would consider them based on passed events and personal experiences. I know the newer stuff, like the others, is way better than even 5 years ago. They make good power, excellent ride and like arctic cat, have many different options to choose from. Also a clutch like front diff, no lock. They work great, until they don't.
Yamaha. I'm biased towards this brand, as I've owned several throughout the years, and still do today. To me, they are the best 'all around' quad on the market. I've owned both a 2011 Kodiak 450 and a 2014 grizzly 700. If you want small, tough, near bullet proof with economy, the smaller Kodiak is the way to go. Ride is ok, its tuff, and with a 2 speed bullet proof transmission, you'll run out of tractions before you ever run out of torque. Might take you a while to get there, but you'll get there. I know of a Kodiak that had in excess of 12k kilometers of hard sugar bush use. The owner pulled the belt cover one day out of curiosity and found the belt to be like new. For the newer grizzly 700, its the best machine I've ever owned. The ride is adjustable (like many others) and can be set of firm, super ground clearance, or soft for a Polaris like ride. Front locking diff, however, it can be a little tricky to engage and requires forward motion and wheel turning to sometimes lock it in. Power steering is huge, but most bikes have it now. Fit and finish is the best out there IMHO. Reliability is the best thing they have going for them. They've evolved with the market for the most part, but have stayed true to their roots. While some stuff is new, they always seem to do they're homework and I've never had or seen any issues (driver misuse/neglect not included). However, they do lack options such as a larger engine, two up seating. My 700 is setup for 2 up, but with 2 riders high in the air, even with the bikes low C of G, it can get dicey on hills due to its shorter wheelbase. However, single rider, tight trails in the woods, this thing is right at home. I've put a set of TJD tracks of mine for the winter, and LOVE this machine.
Chinese. There are many more of them popping out of the wood work, some for WAY less than the major manufacturers. STAY AWAY. Some build crap, others build some ok ones. However, in 10 years, the factory support probably won't be there, and you'll be stuck with a bike you paid 8k for with a broken CV boot or worn belt and nobody will have parts to fit it. You've been warned.
And can't put up a wordy post without a picture.
